Quality Control

Our Oxygen is produced and tested to meet stringent industry-specific standards, including medical (USP, EP), aviation (ABO), and high-purity industrial grades. Every batch undergoes rigorous analysis for purity, moisture, and hydrocarbon content. A comprehensive Certificate of Analysis (COA) is provided with each shipment to guarantee compliance with your specifications and relevant safety regulations.

Storage

Preserve in a tightly closed container, protected from light. Store compressed gas cylinders upright in a well-ventilated, cool, dry, and fire-resistant area, away from combustible materials, heat sources, and direct sunlight. Keep container valves closed when not in use. Liquid oxygen (LOX) must be stored in specially designed vacuum-insulated containers to maintain cryogenic temperatures. Always segregate from flammable gases and oils.
